So, my sister is having the same problem my DS has, except worse. Her power switch is loose, doesn't feel like the spring is working anymore, and her power will not turn on when she moves it. We called Nintendo and they said that the damage was not covered in the warrenty. Fuckers. I was thinking of buying a tri-wing screwdriver to pop it open to see what is going on with it. Would this be good to do or not? Or does anyone know what has happened to it? Thank you very much.
